1.5 Circuits
SLC Communication Loop
One SLC loop is provided standard on the FACP main circuit board. A second SLC loop is avail-
able by plugging the optional SLC module into connector J3 on the main circuit board. SLC loops,
configurable for NFPA Style 4, 6 or 7, provide communication to addressable detectors, monitor
(initiating device) and control (output device) modules. Refer to the SLC Wiring Manual for infor-
mation on wiring devices.
Output Circuits
The following output circuits are available on the FACP:
• Special Application Power
• 24 VDC Resettable (smoke detector power) output - 1.5 amps maximum
• 24 VDC Nonresettable power output #1 - 1.5 amps maximum
• 24 VDC Nonresettable power output #2 - 1.5 amps maximum
• 24 VDC Battery Charger (up to 26 AH batteries)
